A4900 - High Voltage Three Phase Gate Driver

Datasheet Summary

Description

The A4900 is a high-voltage, high-speed, power IGBT or MOSFET driver providing three independent half-bridge channels for three-phase applications.

A bootstrap capacitor is used to provide the above battery supply voltage required for N-channel MOSFETs or IGBTs used as high current switches.

Features

  • High voltage 3-phase gate drive.
  • Floating high-side gate drive to 550 VDC supply.
  • Tolerant to high voltage slew rates.
  • Cross-conduction protection with fixed dead time.
  • 15 V gate drive supply voltage.
  • TTL compatible logic inputs.
  • Undervoltage detection.
  • Overcurrent detection with integrated fault blanking.
  • Overtemperature shutdown.
  • Matched propagation delays.
  • Detailed fault reporting Package: 44-p.
